You have to select the subtitles that should be played by setting the
current-text property. To get information (e.g. language) about
the different subtitle streams you can use the get-text-tags and
get-text-pad action signals.

The order of the subtitle streams as exposed by playbin2 has no real
meaning, the first ready-to-displayed subtitle gets number 0, the next
number 1, etc. This could be different every time
